Intel Core i3-7100U vs Intel Celeron J4115 vs Intel Core i5-7260U

Intel Core i3-7100U

The Intel Core i3-7100U is a dual-core processor of the Kaby Lake architecture. It offers two CPU cores clocked at 2.4 GHz (without Turbo Boost) and integrates HyperThreading to work with up to 4 threads at once. The architectural differences are rather small compared to the Skylake generation, therefore the performance per MHz should be very similar. The SoC includes a dual channel DDR4 memory controller and Intel HD Graphics 620 graphics card (clocked at 300 - 1000 MHz). It is manufactured in an improved 14nm FinFET process at Intel. Compare to the old Skylake Core i3-6100U, the i3-7100U offers a 100 MHz improved clock speed.

 Architecture

Intel basically uses the same micro architecture compared to Skylake, so the per-MHz performance does not differ. The manufacturer only reworked the Speed Shift technology for faster dynamic adjustments of voltages and clocks, and the improved 14nm process allows much higher frequencies combined with better efficiency than before.

Intel Celeron J4115

The Intel Celeron J4115 is a quad-core SoC primarily for inexpensive mini PCs and was announced late 2017. It runs at 1.8 GHz to 2.5 GHz (Single Core Burst) and is based on the Gemini Lake platform. Similar to the Apollo Lake predecessors, the chip is manufactured on a 14 nm process with FinFETs but offers slightly improved processor cores, double the amount of L2 cache, all in a smaller package. Partial Wi-Fi 5 support is baked into the chip. Besides four CPU cores, the chip also includes a DirectX 12 capable GPU as well as a DDR4/LPDDR4 memory controller (dual-channel, up to 2400 MHz). The processor is not replaceable as it is directly soldered to the mainboard.

Architecture

The processor architecture ist still called Goldmont Plus. Compared to the older Goldmont cores in Apollo Lake, they feature a larger L2 cache (now 4 MB). That means the per-clock-performance should be a bit better, but not anywhere near the Core CPUs like Kaby Lake Y.

Performance

The average J4115 in our database only just matches the Core i5-4260U, a somewhat more power-hungry SoC that saw the light of day in 2014, in multi-thread performance. This means the Celeron is a very basic CPU that isn't really ready to handle anything beyond the most basic tasks such as writing e-mails and listening to Spotify.

Graphics

The UHD Graphics 600 (Gemini Lake) is based on Intel's Generation 9 architecture, which supports DirectX 12 and is also used for the Kaby Lake / Skylake / Apollo Lake graphics adapters (like HD Graphics 520). Equipped with 12 EUs and a clock of up to 750 MHz, the performance should be roughly on par with the older HD Graphics 500 (Apollo Lake).

The chip also includes an advanced video engine with hardware support for the playback of VP9 and H.265 (8-bit color-depth).

Power consumption

Like most other J-class Intel processors, the Celeron has a default TDP (also known as the long-term power limit) of 10 W. This is low enough to allow laptop makers to build passively cooled laptops, mini-PCs, tablets and other gadgetry around the chip.

The Intel Celeron J4115 is built with one of the old 14 nm Intel processes for poor, as of early 2023, energy efficiency.

Intel Core i5-7260U

The Intel Core i5-7260U is a fast dual-core SoC for notebooks and Ultrabooks based on the Kaby Lake architecture and was announced in January 2017. The CPU has two processor cores clocked at 2.2-3.4 GHz (two cores also up to 3.4 GHz). The processor can execute up to four threads simultaneously thanks to Hyper Threading. It is also equipped with an Intel Iris Plus Graphics 640 GPU with 64 MB eDRAM, a dual-channel memory controller (DDR4) as well as VP9 and H.265 video decoding as well as encoding. The chip is still manufactured in a 14nm process with FinFET transistors.

Compared to the Core i7-7360U, the i5-7260 does have lower CPU (-200 MHz Turbo, -100 MHz Base) and GPU (-50 MHz) clocks.

Architecture

Intel basically uses the same micro architecture compared to Skylake, so the per-MHz performance does not differ. The manufacturer only reworked the Speed Shift technology for faster dynamic adjustments of voltages and clocks, and the improved 14nm process allows much higher frequencies combined with better efficiency than before.

Performance

At 2.2-3.4 GHz, the Core i5-7260U has much lower clocks compared to the old Core i5-6267U (2.9-3.3 GHz), but has slightly higher Turbo clocks. Similar to the 6267U, the i6-7260U can also use the 64 MB eDRAM, which should increase the performance in some scenarios.

Graphics

The integrated Intel Iris Plus 640 Graphics is the GT3e model of the Kaby Lake GPU (Intel Gen. 9.5). It has 48 Execution Units running at 300-950 MHz (i7 models up to 1050 MHz) and the performance is comparable to a GeForce 920MX thanks to fast eDRAM cache. However, there aren't any significant improvements compared to the old Iris Pro 540, so modern games can often not be played smoothly or only at the lowest or medium settings, respectively.

Contrary to Skylake, Kaby lake now also supports H.265/HEVC Main 10 with a 10-bit color depth as well as Google's VP9 codec. The dual-core Kaby Lake processors announced in January should also support HDCP 2.2.

Power Consumption

The chip is manufactured in an improved 14nm process with FinFET transistors, which improves the efficiency even further. Intel still specifies the TDP with 15 Watts, which is typical for ULV chips. Depending on the usage scenario, the TDP can vary between 7.5 (cTDP Down) and 25 Watts.
